The study identifies a gap in understanding the impacts of SSW events on surface weather patterns over Eurasia. The study highlights the need for improved climate models that can accurately capture the relationship between stratospheric anomalous behavior and surface weather patterns. The study identifies the importance of accurately representing stratosphere-troposphere coupling strength to reliably capture the surface impacts of stratospheric variability.

Future research should focus on improving the performance of climate models in simulating surface weather patterns. The use of stratospheric nudging experiments could be applied to other climate models to improve their performance. Future research should investigate the relationship between SSW events and surface weather patterns in other regions, such as North America.

The nudging experiments exhibited adverse effects, including a pronounced cold bias developed over Alaska. The study used a limited number of SSW cases, which may not be representative of all SSW events. The model’s tendency to produce overly strong coupling between the stratosphere and upper troposphere in certain regions may limit the accuracy of the results.

The study faced challenges in accurately representing stratosphere-troposphere coupling strength. The model’s tendency to produce overly strong coupling between the stratosphere and upper troposphere in certain regions limited the accuracy of the results. The study had to minimize the influence of tropical regions on surface weather.
